摘要
人工预先破冰是防凌渡凌工作中常采用的比较有效方法之一.在几个工程实践和现场实验的基础上,对人工破冰河段的选择、破冰长度和宽度的确定、冰孔布设、单孔药量以及破冰的实验进行了系统的总结,提出了工程防凌渡凌的冰盖爆破的各项参数和指标,以及爆破技术的施工措施和步骤.
Anticipated ice blasting is an effective method frequently adopted in the struggle against ice jam. Based on many practices and in\|situ tests, in this paper a systemic summarization is made about choosing the blasting range, confirming the width and length of a blasting, determining the distribution of blasting holes and the powder amount in a single hole, as well as blasting test.
